SCA-X are check valves with a built-in shut-off valve function. SCA-X valves are available in angleway versions.CHV-X are check valves only. CHV-X are available in both angleway and straightway versions.The valves are designed to open at very low differential pressures, allow favorable flow conditions and are easy to disassemble forinspection and service.The SCA-X is equipped with vented cap and has internal back seating enabling the spindle seal to be replaced whilst the valve still underpressure.Laser cut V-ports provide excellent opening characteristics (SCA-X/CHV-X 50-125).The valve cone has a built-in flexibility to ensure a precise and tight closing towards the valve seat. A well-balanced dampening effectbetween the piston and the cylinder gives an optimal protection during low loads and against pulsations.
